AUSTIN, Texas — Steps from a crush of scooters and throngs of tech hipsters munching on food truck fusion tacos, HBO has created another universe.

Visitors talk in hushed tones and line up for the blessing of a woman in a long red gown. She whispers in their ear, and they quietly walk away, clutching the pin she's handed them, cast in the shape of the "hand of the throne," straight from the land of Westeros in "Game of Thrones." A robed chorus chants a familiar score astride an iron throne, protected by soldiers holding heavy spears, and shafts of light pierce the cavernous space. Just out the doors in the heavy Austin air, visitors are accosted by Wildlings wearing furs and shells, as a Khal Drogo look-alike threatens heavily armed "unsullied" warriors.
